Re: Speedo wrong, but is that all?
Live and learn. Here I've been thinking that the one piece axle came
in with the TJ - now I've got to revise my shopping list again, since
I'm looking for a SWB ride now. Took the wife back in the hills to
look at the leaves turning and she decided that both she and the dog
would really like it if I got something to supplement the MJ. I guess
we all win one sometime <g>.

Ah, that would explain it... I had been looking at the differential housing
itself for a clue instead of outside on the axle tubes... plus I was looking
from the front, so I didn't see that vacuum motor-ish thingy hiding away.
So I jacked up one wheel, started the car, and put it into 4WD... this
seemed to do the trick, I was able to spin the wheel and subsequently rotate
the driveshaft. Two turns of the wheel and I got a 3.07 ratio, which is
excellent news for me. Thanks again to everyone who helped me sort this
out!
I still need to yank the current speedo gear and see what's up with that,
but if that's why it's wrong I have to wonder how the wrong gear got put in
there. If they swapped in a new transfer case and/or transmission, I hope
that isn't a recipe for disaster... like if they put in parts that were
originally meant for a smaller engine Jeep if it's the kind of thing where
they won't survive behind the 4.0L for very long. Hopefully that's not the
case, but I suppose looking at the speedo gear might give a clue.
Especially if it's a gear for one of the other factory ratios that were
available, maybe the entire transfer case was swapped out including the old
speedo sender and replaced with one originally in a smaller engine Jeep.
Eventually I'll get to the bottom of this, but for now it's good to know
that the 4WD functionality is still there. Thanks again, everyone!
